IW3713-44Ref

The IWC Pilot's Watch Doppelchronograph ref. 3713, manufactured from about 1996 to 2005, was the second pilot watch by IWC to incorporate a split-second chronograph. It was crafted in stainless steel, yellow gold, or platinum with multiple dial and day-disc language variations; the steel model came on a strap or bracelet, and five platinum pieces were made with bracelets. After 2003, the 3713 featured only Spitfire-style dials, exemplified by the stainless steel ref. IW3713-44 with its silver 'Spitfire' dial.
